Winter Highlands
Driving in Iceland

The honest answer is: almost certainly not independently, and definitely not safely in a standard vehicle. All major highland F-roads — Kjölur (F35), Sprengisandur (F26), F208 to Landmannalaugar, F88 to Askja and F249 to Þórsmörk — are officially closed from late October until June or July.

What is sometimes possible in winter, with the right vehicle and conditions:

Highland road closures are not bureaucratic caution — they reflect genuine, life-threatening hazards that build up as the season turns. Road conditions in Iceland can change overnight, and highland tracks that were navigable in October can be buried under three metres of drifted snow by November.

Highland snow is categorically different from coastal Iceland snow. The interior plateau sits above the marine layer that moderates coastal temperatures, meaning the highlands experience far colder, drier conditions — with all the challenges that brings. Whiteout conditions (where blowing snow makes the horizon invisible) can form within minutes even in otherwise clear weather.

Sastrugi — wind-sculpted ridges of hard-packed snow — form across highland tracks and can be rigid enough to cause serious damage to a vehicle attempting to drive through them. These can develop overnight and are invisible until you are already on top of them.

In mid-winter, highland snowpack typically ranges from 1–4 metres at lower elevations to 8–12 metres at mountain passes. Snow can continue falling into June at higher elevations — the reason some F-roads don't open until July. Even in summer, a late storm can close a highland route for several days.

Iceland's highland rivers originate in glaciers — and glacial rivers behave in counter-intuitive ways. In winter, the reduced meltwater means rivers run lower and appear more manageable. But this is deceptive: river ice forms unevenly, ice shelves can collapse under vehicle weight, and river beds remain highly unstable even under a frozen surface.

The most dangerous period for river crossings is actually spring— March to May — when glacial melt accelerates dramatically in the afternoon sun. A river that was knee-deep in the morning can be waist-deep and fast-moving by 3pm. This is why Iceland's highland rescue teams see their busiest period not in winter, but in spring and early summer.

If you encounter a river crossing, regardless of season:

• Always stop and walk the crossing on foot before driving
• Test depth and current with a walking pole or sturdy stick
• If depth exceeds your knees, the current is dangerous
• Enter at a 45-degree angle pointing slightly upstream
• Drive slowly and steadily — no sudden movements
• If you feel the vehicle shift, don't panic: steer into the current
• Never drive through a crossing alone — have spotters on both banks

Iceland sits at the convergence of Arctic and North Atlantic weather systems, making its highlands one of the most meteorologically extreme environments in Europe. Iceland weather can change from calm sunshine to a severe blizzard in under two hours, and highland terrain offers zero shelter.

Not all 4×4 vehicles are equal in Iceland's highlands. Understanding the difference between a standard 4×4 rental and a purpose-built Super Jeep is critical for planning your winter highland trip.

One of the most effective techniques for winter off-road driving in Iceland is airing down— significantly reducing tire pressure to increase the tire's contact patch with the snow surface. This dramatically improves flotation and grip.

Mobile phone coverage in the Icelandic Highlands is effectively zero. There are no cell towers in the interior. Satellite communicators are not a luxury item — in winter highland conditions, they are the only way to call for help if something goes wrong.
